Abstract

A packaging laminate (4) according to the invention comprises a base polymeric foil (1) on which in the desired places there is applied an adhesive layer (2), which in turn is covered by a weld layer (3).
The laminate (4) will hereby be able to function in a self-sealing, re-openable and re-closable manner, in that a separation occurs between the adhesive layer (2) and the weld layer (3).
In this way there is achieved a surprisingly simple and effective re-closure, either by the adhesion of the adhesive layers to each other (fig. 1) or by the adhesion of the adhesive layer with other materials (5) (fig. 2).
